This invention relates to an improvement 7 in valve-springlifters suchas are commonly employed for lifting the valve-spring of explosiveengines to remove the valvepin, theobject being a simple arrangementofparts whereby the device will remain in position and through whichsufiicient force may be easily applied to readily compress the springfor an adjustment of the valve; and the invention consists in theconstruction as hereinafter described and particularly recited in theclaims. V

In carrying'out my invention, I employ a cuplike member 8 either roundor rectangular, formed on one side with an outwardly projecting fork 9.(lo-acting wlth this cup is a cap member 10 corresponding in shape tothe cup member so as to telescopically slide therein or thereon. Thiscap member.

is also formed with an outwardlyprojecting fork 11. Within the 'cup andbearing upon the spring-seat collar 17,
